Influential in the world of music during the first half of the
twentieth century, he was, in addition to being a composer/conductor,
Associate Conductor of the New York Philharmonic for many years, a
distinguished musical educator (Meredith Willson was one of his
students), and first director of the Tanglewood Festival in
Stockbridge, Massachusetts. He was also a pioneer in music on film,
leading the orchestra for 1926's "Don Juan," the first feature film to
have a synchronized musical score, and leading the New York
Philharmonic in one of the sound shorts that was shown at the film's
premiere showing in New York.
